It might be a strange offer to make, if it had been made by a newbie then I would have seen it as suspicious.
As the OP has posted 43 reviews on UKP he is a valuable contributor here. People can take the piss if they want but it doesn't really help, I'm not sure if it's the same member but there is a member on UKP who a few months ago 'lent' his hotel room to another member to use for a punt. That member was very grateful & it was a generous offer to make.
Thanks for the offer TG but I'm on hols for those dates anyway
